@bnoordhuis I wonder if it may be a good opportunity to write our first C++ test. |

Nah, gtest didn't work out. It was simpler to just write an test addon. |

Out of curiosity, is it viable to use a technique similar to https://groups.google.com/d/msg/v8-users/JmhzmswiqvM/IC6UtV5FEC4J so that --expose-gc doesn't have to be passed?

idk, seems to be a legit use of RequestGC here

LGTM. Does CI run these tests? |

Can I suggest you make this a counter and check that it's > 0 in FreeCallback?

LGTM |
FreeCallback should be invoked on the storage disposal (`ArrayBuffer`), not when the view (`Uint8Array` or `Buffer`) is disposed. This causes bug and crashes in addons which create buffers and store only slices of them.
